Overview
The custom n8n node for managing invoices allows users to update existing invoice records in an inventory management system. This node is particularly beneficial for businesses that need to maintain accurate financial records and ensure that their invoicing reflects the latest changes, such as updated line items or payment terms. Common scenarios include adjusting invoice details after a sale, correcting errors in previously issued invoices, or updating due dates based on customer agreements.
For example, a user might utilize this node to change the due date of an invoice after negotiating new payment terms with a client, or to add comments regarding payment instructions.
Properties
| Name | Meaning |
|---|---|
| Invoice ID | The unique identifier for the invoice that needs to be updated. |
| Invoice Details | A collection of details about the invoice, including: |
| - Invoice Number: The number assigned to the invoice. | |
| - Invoice Date: The date when the invoice was issued. | |
| - Due Date: The date by which payment should be made. | |
| - Tax Rate: The applicable tax rate for the invoice. | |
| - Currency: The currency in which the invoice is issued. | |
| - Comments: Any additional notes or comments related to the invoice. | |
| Invoice Line Items | A fixed collection of line items associated with the invoice, where each line item includes: |
| - Product Code: The code identifying the product being billed. | |
| - Quantity: The number of units for the line item. | |
| - Unit Price: The price per unit of the product. | |
| - Discount Percentage: Any discount applied to the line item. |
Output
The output of the execute() method will typically return an array containing the updated invoice data in JSON format. Each entry in the output will represent the result of the update operation, which may include confirmation of the updated fields or any error messages if the update fails. If the node can output binary data, it would generally represent files or documents related to the invoice, such as PDF versions of the updated invoices.
Dependencies
- An API key credential is required to authenticate with the inventory management system's API.
- The node relies on the availability of the Unleashed API for performing operations related to invoices.
Troubleshooting
Common issues users might encounter include:
- Invalid Invoice ID: If the provided invoice ID does not exist, the node may throw an error indicating that the invoice could not be found. To resolve this, ensure that the correct invoice ID is being used.
- Missing Required Fields: If mandatory properties like Invoice ID or line item details are not provided, the node will likely fail. Users should verify that all required fields are filled out correctly.
- API Authentication Errors: If the API key is incorrect or missing, the node will not be able to connect to the service. Ensure that the API key is valid and properly configured in n8n.
